The vector torque control algorithm of synchronous reluctance motors (SynRM), which are deeply saturated electrical machines, is presented. The control algorithm design is based on a motor mathematical model with polynomial approximations of the flux-coupling functions that do not use trigonometric functions or multidimensional tables. The structure of the SynRM control system allows for the analytical and numerical formalization of the maximum torque per Ampere optimization. The resulting optimization procedure is much simpler than the existing ones and does not require long-term experimental tests, and is easily automated. The results of the vector control system testing with the proposed optimization algorithm confirm that it reduces power consumption in the torque zone by up to 50-70 % of the nominal value compared to the control system with constant flux coupling. At the same time, asymptotic tracking of the reference torque and flux-forming component of the stator current is achieved. The study results show that optimization has a greater effect for motors of lower power. References 16, figures 6, table 1.
